How long is the galvanic isolator subjected to vibration testing in each orientation?

The standard for galvanic isolators, particularly in marine applications, specifies that these devices must undergo vibration testing to ensure they can withstand the rigors of the marine environment. The correct duration for vibration testing of galvanic isolators in each orientation is indeed four hours. This testing is crucial since galvanic isolators are often installed in areas prone to vibration, such as on boats and vessels.

Testing for this length of time confirms that the isolator will maintain its operational integrity and performance despite prolonged exposure to real-world conditions. This duration allows engineers to thoroughly assess the component's ability to handle the stresses and potential failures that could arise during normal use in a marine environment.
